Hello forum!
I have a one old sh|t: Dell Inspiron mini 1011. It have been at the balcony during several years and became locked because of its main and CMOS batteries death - its BIOS locked me from any changes every start up (asked for admin password - it was never installed by me, but came automatically after CMOS data was destroyed). No chance to unlock it by password generators - I was tried them all.
I came into this forum and start at this page: "https://www.bios-mods.com/bios-recovery/phoenix-bios-recovery". Found good tips and tricks about Fn+B, Win+B and the END buttons at start up. I tried all combinations combined with AC cable plug-in (still without a new CMOS battery), and at one moment - BANG! - this brick started again without password! This moment I plugged in a new CMOS battery - to prevent BIOS from expose password. No annoying passwords anymore
Well, I used a Phoenix CRISIS Recovery utility (also from "https://www.bios-mods.com/bios-recovery/phoenix-bios-recovery"). I just prepared a 2GB SD card with MS-DOS 7.10 (without HIMEM.SYS driver!), then put there three files: MINIDOS.SYS, PHLASH16.EXE (from recovery utility) and BIOS.WPH. The last one (A06 bios_mod.rom just renamed to BIOS.WPH) came from Sml6397's post #3 from this thread (all thanks are going to him!).
After restart (without HDD - only with SD card in USB card reader) I came into DOS with Norton Commander, then I started a file PHLASH16.EXE and it automatically found a file BIOS.WPH - the process of flashing was started immediately. It have been continued about two minutes - the program showed me a blocks of memory those were reflashed one by one. After all, laptop demonstrated a black screen, but restarted in 10 seconds. I was impressed by new menu tab "Intel" in BIOS with many new functions. Some of them work good, some are absolutely decorative (like AHCI settings - it doesn't want to start with any HDD). Anyway I unbrick my pet and want to use it for internet downloads and something like that. When I disconnect and reconnect a new CMOS battery several times - it was no bloody password (!) and I hope it never comes again. Also hope my experience will help somebody else with reparation of laptop without unsoldering BIOS chip. Really: theese ingeneers from Dell are stupids - they attached a hardware security level as for ATM cash machine to the chipest netbook... I killed a week for it... Bloody he||...
So my bigest thanks are to BIOS mod author - Sml6397 !
And many good years to this useful forum!
